no
they have two shells held together by hinges and strong muscles
they are called bivalves .(:
The hinge ligament hold the two shells together as well as the adductor muscles which controls the opening and closing of the bivalve.
Various types of shells can be found in the ocean, including gastropod shells, bivalve shells, and cephalopod shells. These shells are created by different types of marine animals and come in a wide range of shapes, sizes, and colors.
posterior and anterior adductor muscles
there are millions of types of seashells in the world Some of the common sea shells are ~ Mother of pearl shell ~Ark shell ~Script Shell ~Giant clam (Tridacna Gigas) ~Gastropod ~Kapis Hope this can help.....
Cone shells belong to the Kingdom Animalia, within the phylum Mollusca. They are marine gastropod mollusks known for their beautifully colored shells and potent venom used for hunting prey.
Valves
Bivalves have strong muscles in order to hold their shells closed.
Yes, fusus is a type of fossil gastropod. Fusus are pointed spiral shells that belonged to a group of marine snails known as gastropods, which lived millions of years ago. They are commonly found in sedimentary rocks and are often used by paleontologists to study past marine environments.
The clam does. Clams and other bivalves have very strong muscles that hold the shells tightly closed whenever they're in danger.
Clams close their shells with powerful adductor muscles which pull the two valves together. A springy ligament at the hinge pulls the shell open when the muscles relax. Just like us, the clam needs to use nerve cells to signal the muscle to do its thing.
